Enerflow opened in September 2009 on a 30-acre campus vacated by Native American Industries. About 45 people now work at Enerflow and many are former workers of National Oilwell Varco, which closed its Tulsa plant last year, Energlow officials said.

The combination of a vacant 100,000-square-foot plant and available work force convinced company leaders to pick Broken Arrow over Houston, said general manager John Powers.

"The building was almost ideal," Powers said. "I'd been looking for six months."

The company is hiring welders, mechanics and automotive technicians that can earn $14 to $18 per hour. Some management and engineering jobs also will be needed and can pay up to $120,000, Powers said.

It probably won't take a decade to grow the company to more than 500 employees, he said.

"It's a big jump," Powers said. "We attribute that to the continued strong oil and gas industry not only in Oklahoma but in the Midwestern region of the United States."

Enerflow qualifies for up to $6.19 million in payroll rebates through the state's Quality Jobs program.

Enerflow is based in Broken Arrow but affiliated with a Canadian firm of the same name.

Cimarron Energy was founded in 1976 in Guymon by John Moore and is now based in Norman. The company qualifies for up to $2.2 million in payroll rebates over 10 years.

Cimmaron employs about 225 at plants in Oklahoma and Colorado, said Trey Moore, the company's vice president of operations and the founder's son.

"Last year we had to downsize but now we are ramping back up," Trey Moore said. "We've been able to position ourselves to take advantage of new shale plays across the U.S."

He said the company is hiring welders, purchasing, human relations staff and other office personnel.
